In this paper, we consider solutions of Toeplitz systems Au = b where the Toeplitz matrices A are generated by nonnegative functions with zeros. Since the matrices A are ill-conditioned, the convergence factor of classical iterative methods, such as the Richardson method, will approach 1 as the size
We study the performance of parallel solution of a block-tridiagonal linear system adopting the ลฝ . block cyclic reduction BCR method. We develop a parallel code on Fujitsu VPP500 to solve a ลฝ . block-tridiagonal BT linear system and measure the speed of the parallel code on VPP500r28 at RIKEN in or
